Politics and contemporary poetry
The paper is a Meditation (variant on the manner of Aurelius and
Descartes) concerning the immediate situation, in the United States, of
poetry as a discourse of political engagement. As such, the paper is
a highly personal one. It means to offer an account of the peculiar
limits within which contemporary poetry in the United States is forced
to get carried on, as well as an explanation of the context in which
those limits were defined. It also suggests possible ways to exploit
the special resources of contemporary poetry (formally and socially
conceived) for political discourse and social critique. The paper is
most centrally concerned to illuminate the special kinds of critical
reflection which contemporary poetry, by virtue of its marginal
position, makes available. The paper's two main sections involve
the author's own reflexive analysis of his encounters with certain
texts by Hans Magnus Enzensberger, Theodor Adorno, and Carolyn Forche
S-band microcircuit power amplifier
Research, design, development, and fabrication of a two-stage, solid-state, microcircuit power amplifier operating in the 2.25 GHz region of the S-band are summarized. Output is typically 7.0 watts for an input of approximately 400 mw. Input stage is an MSC 3001 transistor; output stage is an MSC 3005 transistor. Input VSWR is 1.4:1.0, or less. Efficiency of 33.3 percent or more is achieved. Second and third harmonic suppression is 30 db. Operating power is 28 VDC. The entire unit has a length of 3.80 inches, a width of 2.08 inches, and a height of 1.00 inch
Generalised fractional diffusion equations for subdiffusion on arbitrarily growing domains
Many physical phenomena occur on domains that grow in time. When the
timescales of the phenomena and domain growth are comparable, models must
include the dynamics of the domain. A widespread intrinsically slow transport
process is subdiffusion. Many models of subdiffusion include a history
dependence. This greatly confounds efforts to incorporate domain growth. Here
we derive the fractional partial differential equations that govern
subdiffusion on a growing domain, based on a Continuous Time Random Walk. This
requires the introduction of a new, comoving, fractional derivative.Comment: 12 pages, 1 figur
Discretization of Fractional Differential Equations by a Piecewise Constant Approximation
There has recently been considerable interest in using a nonstandard
piecewise approximation to formulate fractional order differential equations as
difference equations that describe the same dynamical behaviour and are more
amenable to a dynamical systems analysis. Unfortunately, due to mistakes in the
fundamental papers, the difference equations formulated through this process do
not capture the dynamics of the fractional order equations. We show that the
correct application of this nonstandard piecewise approximation leads to a one
parameter family of fractional order differential equations that converges to
the original equation as the parameter tends to zero. A closed formed solution
exists for each member of this family and leads to the formulation of a
difference equation that is of increasing order as time steps are taken. Whilst
this does not lead to a simplified dynamical analysis it does lead to a
numerical method for solving the fractional order differential equation. The
method is shown to be equivalent to a quadrature based method, despite the fact
that it has not been derived from a quadrature. The method can be implemented
with non-uniform time steps. An example is provided showing that the difference
equation can correctly capture the dynamics of the underlying fractional
differential equation

The Meaning of Prophets and the Making of Trolls: 19th-Century Reception of Charles Dickens’ Barnaby Rudge
Comprised of arson, betrayal, murder, abduction, exploitation, rebellion, and bastardry, Charles Dickens’ Barnaby Rudge is all but a boring read. Set during the Gordon Riots of 1780, Dickens’ fifth novel was published in installments beginning in 1841, each week promising a new cast of characters and events having to do with the anti-Catholic uprisings that had taken place nearly 60 years prior. These uprisings, led by Lord George Gordon, had originally begun as orderly protests over Catholics serving in the British Army; however, they quickly evolved into full-scale riots, with crowds of over 50,000 people burning down prisons, churches, and the homes of Irish immigrants. According to critics, the rise and dominance of periodicals in this period amplified Dickens’ interest in the Riots, which were widely read about and recorded in daily newspapers and political magazines. As Iain McCalman points out, Dickens’ inspiration for the novel may have even come from a coroner’s report that was featured in The Times in 1838 – one that described a man strangling himself in an obscure London Tavern after revealing his revolutionary past. The man, it turned out, had been Lord Gordon’s secretary during the Riots, and this disturbing news bite – along with subsequent others – formed the basis for what would eventually become Dickens’ first historical novel
Fundamental Brainwork. Rossetti Among the Printers
Scholars are well aware that Dante Gabriel Rossetti was seriously concerned that the printing of his work be carried out to his precise expectations. The surviving MS and proof materials for his books are remarkably extensive. This is especially the case with his 1870 Poems and the two 1881 volumes—Poems. A New Edition and Ballads and Sonnets. As with his 1870 volume, Rossetti once again enlisted others to help him with the correction of his two 1881 volumes as they were going through the press. Taking the Ballads and Sonnets volume as an especially clear and dramatic case of Rossetti's creative habits, this essay exposes how meticulous and how significant were the corrections and changes that Rossetti made to that book
